Background: Currently, spectral-domain optical coherence tomography (SD-OCT) appears to be a new type of glaucoma diagnostic tool. Thus, this study aimed to evaluate the effectiveness of glaucoma diagnostic parameters from SD-OCT of patients with different severities of myopia.
Methods: This was a cross-sectional study.
Article Synopsis
- The research aimed to develop a clinical diagnostic model for primary open-angle glaucoma (POAG) using frequency-domain optical coherence tomography (FD-OCT).
- The study analyzed a total of 232 eyes, comparing retinal nerve fiber layer (RNFL) thickness measurements from healthy individuals and early POAG patients to create and test four diagnostic models.
- Findings revealed that newer area partition models showed better diagnostic accuracy than traditional models, with the simplest model (ONH-N) being especially convenient for clinical use.
Background: High intraocular pressure (IOP) and low central corneal thickness (CCT) are important validated risk factors for glaucoma, and some studies also have suggested that eyes with more deformable corneas may be in higher risk of the development and worsening of glaucoma. In the present study, we aimed to evaluate the association between corneal biomechanical parameters and asymmetric visual field (VF) damage using a Corvis-ST device in patients with untreated normal tension glaucoma (NTG).
Methods: In this observational, cross-sectional study, 44 newly diagnosed NTG patients were enrolled.

Objective: To investigate the clinical characteristics of the eyes with unilateral disc hemorrhage (DH) in normal tension glaucoma (NTG) patients.
Methods: 37 normal-tension glaucoma patients with unilateral DH were studied. Extensive parameters were analyzed to evaluate which parameters differ significantly between the DH eyes and the companion eyes.
Background: Optical coherence tomography (OCT) is a high resolution noncontact imaging modality which can quantitatively detect the optic disc and retinal structure. This study was designed to evaluate the diagnostic capability of parameters of the optic disc, retinal nerve fiber layer thickness, and ganglion cell complex (GCC) using a new technology called Fourier-domain OCT (FD-OCT) for early primary open angle glaucoma (POAG) patients.
Methods: Two groups of patients, early perimetric damage POAG and normal subjects were included in this observational cross-sectional study.
Objective: To evaluate the difference of the peripapillary atrophy between two eyes of unilateral visual field defect in each of patient with primary open-angle glaucoma (POAG) and normal tension glaucoma (NTG).
Methods: This study included 40 eyes with unilateral visual field defect in patients with POAG (20 cases) and NTG (20 cases). Color stereo optic disc photographs were morphometrically evaluated by a video camera and a computer system.

Objective: To evaluate the variety of peripapillary atrophy (PPA) and its relationship with visual field among primary open angle glaucoma (POAG), normal tension glaucoma (NTG), and normal subjects with glaucoma-like disk (GLD) that had no evidence of visual field defect and retinal nerve fiber layer defect.
Methods: The study included 42 eyes of 42 patients with POAG, 40 eyes of 40 patients with NTG, and 45 eyes of normal subjects with GLD. Stereo color optic disc photographs were morphometrically evaluated by a video camera and computer system.
Objective: To investigate the changes of the sectorial discs and visual fields, and their interrelationships in patients with normal tension glaucoma (NTG).
Methods: 26 patients with NTG were undergone the optic nerve and visual field examinations with HRT-II and HFA II in a time interval of less than 5 months. The parameters in the study including cup shape measure (CSM), rim area (RA), rim volume (RV), mean cup depth (MCD) and cup volume index (CVI) were compared between the global discs and the sectorial discs in eyes with the evidences of preperimetric or early visual field defect (MD < or = 4 dB).
[Clinical observation of needle revision and 5-fluorouracil subconjunctival injection on the dysfunctional filtering blebs].

Objective: To investigate the efficacy of needle revision with 5-fluorouracil (5-FU) on the dysfunctional filtration blebs after trabeculectomies and to assess the factors that may impact the success.
Methods: Fourty eyes of 34 patients underwent the needle revision of the malfunctional blebs with 5-FU at clinic visits in 2 - 8 weeks immediately after trabeculectomies and were followed up for 12 weeks.
Results: After revision through needling procedures, the blebs were diffused and elevated in 26 eyes, thinned and multisystem in 9 eyes, thickened and focalized or invisible in profile in 5 eyes.
